5.4 Audio Only Source
Any input can be set up as an audio only source by connecting a desired stereo
(S/PDIF) digital audio source to a nominated digital coax (S/PDIF) RCA socket (1 to 8)
and leaving the associated HDMI input port vacant. The audio only source can then be
selected as per normal (source selection 1 to 8) and will transmit the selected audio
together with a “black” video signal.
5.5 Flexible Audio Routing
Flexible audio routing within the system allows audio from any of:
HDMI sources
Digital Coax (S/PDIF) audio input connectors on the LTB1 / LTB1E Breakouts
Digital Coax (S/PDIF) audio input connectors on the LT88 / LT88E
to be routed to the Stereo RCA analog output connectors on the LT88 / LT88E.
The source range for the selected audio inputs under this feature becomes:
HDMI input ports: 1 to 8
LTB1 / LTB1E Breakouts: 9 to 16
LT88 / LT88E: 17 to 24
This feature is activated by specific RS232 commands. Refer to separate
documentation for further detail.
[notes: If Multichannel Audio is selected as the source for the RCA analog outputs then
that output will be muted. S/PDIF audio performance from LTB1 / LTB1E breakouts
may be unreliable in instances where the Cat5e / Cat6 cabling to them exceeds
approximately 50 metres or is subjected to electrical interference.]
5.6 Audio Sync Delay
Each pair of stereo RCA audio output ports has programmable audio sync delay
capability which may be useful to bring the audio from these ports and the displayed
video closer to synchronism. This feature is activated by specific RS232 commands.
Refer to separate documentation for further detail.
